Diagnosis. The species of this subgenus are identified by a combination of the following characters (both sexes): head and mesosoma with integument dark brown to black, never with yellow areas ( Figs. 1, 3 , 5, 7 , 9, 11 , 13, 15 , 17, 19 , 21, 23 , 25, 27 ); metasoma with metallic reflections (in some species) ( Figs. 2, 4 , 18, 20 , 22, 24 , 26, 28 , 35 and 36 ), wing membranes translucent ( Figs. 2, 4 , 6, 8 , 10, 12 , 14, 16 , 18, 20 , 22, 24 , 26, 28 ) and maxillary palpus with five palpomeres. Females: basitibial plate with a concavity in the lower half of the primary plate ( Fig. 35 ) (except in C. muralis Fig. 37 ), with secondary plate fused with the primary plate, evidenced by a convexity on the upper half (lateral view). Males: preapical surface of gonocoxite with a papillate projection ( Fig. 38 ).
